+ * config/m32r/m32r.md (movstrsi_internal): Do not expect a
+ return string from m32r_output_block_move.
+ * config/m32r/m32r-protos.h: Make m32r_output_block_move a
+ void function.
+ * config/m32r/m32r.h (INT32_P): Rename to UNIT32_P and remove
+ integer overflow.
+ (ROUND_ADVANCE): Remove signed/unsigned conflict.
+ * config/m32r/m32r.c: Declare prototypes for static functions.
+ (move_src_operand): Replace INT32_P with UINT32_P.
+ (function_arg_partial_nregs): Fixed signed/unsigned conflict
+ in initialisation of 'size'.
+ (m32r_sched_reord): Remove redundant declarations of 'code'.
+ (m32r_output_block_move): Change to a void function.
+ (m32r_encode_section_info): Cast return of
+ TREE_STRING_POINTER to avoid compile time warning.
